Description

Technical Field

[0001] The utility model relates to the technical field of zinc ash processing, in particular to an energy-saving and environmentally friendly zinc ash processor. Background Art

[0002] A zinc ash processor is a device used to process zinc ash. Zinc ash is waste material generated after the zinc layer is removed from the surface of a galvanized steel plate. It contains a large amount of zinc and other metal elements, so a zinc ash processor is needed to process it. In combination with existing literature, a zinc ash processing device (CN217595904U) is provided: it includes a heating barrel, a sealing cover, a mixing device, a connecting pipe, and a condensation recovery device. A sealing cover is provided at the upper port of the heating barrel, a mixing device is provided at the upper end of the sealing cover, the lower end of the mixing device extends into the heating barrel, a condensation recovery device is provided on the side of the heating barrel, and a connecting pipe is provided between the heating barrel and the condensation recovery device. The utility model effectively absorbs condensed zinc ash generated by zinc vapor through an independently developed zinc ash suction device;

[0003] The existing technology has the following problems:

[0004] 1. As described in the above patent, the heating device and the condenser are started, the discharge valve is opened, and the zinc ash is reduced to metallic zinc vapor. The metallic zinc vapor enters the recovery barrel along the connecting pipe. However, the metallic zinc vapor may carry some solid particles in the process of entering the recovery barrel, causing the solid particles and the metallic zinc vapor to be concentrated in the recovery barrel for collection, affecting the subsequent treatment effect.

[0005] 2. Zinc ash and zinc slag are by-products produced during the production process of hot-dip galvanizing plants and electrolytic zinc plants. They need to be heated during processing. Some zinc ash usually contains zinc oxide, chloride and other components. Due to friction and viscosity during the stirring process, some zinc ash is easy to adhere to the inner wall. Long-term accumulation and attachment to the inner wall will reduce the heat transfer coefficient, affect the heat transfer efficiency, and thus increase energy consumption.

[0006] To this end, we proposed an energy-saving and environmentally friendly zinc ash processor to solve the above-mentioned drawbacks. Utility Model Content

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0039] Example: Figure 1 , Figure 2 and Figure 3 As shown, an energy-saving and environmentally friendly zinc ash processor, the motor 3 used in this machine is SGMAH-04AAA41D model, which has the characteristics of high-speed response and high precision, and adopts reasonable structural design and high-quality material manufacturing to ensure the stable operation of motor 3 under long-term and high-load conditions, the fan 7 is Y4-72-2.8A model, adopts advanced design and manufacturing technology, has a high energy efficiency ratio, and adopts noise sound insulation materials and vibration reduction measures to make the noise level low during operation; it includes a processing tank 1 and a recovery box 6, the base 2 is used to support the processing tank 1, open the sealing cover to put the raw materials into the processing tank 1 from the feed port 4, and then close the sealing cover, the personnel can use the control panel 5 to operate the machine, and the internal raw materials are fully stirred and mixed through the stirring and cleaning components. After the sufficient mixing and stirring is completed, the electric heating tube 13 and the condensing tube 15 are started, and the electric heating tube 13 is operated to convert electrical energy into heat energy , thereby increasing the internal temperature of the processing tank 1. At the same time, the insulation board 11 is made of polyurethane, which has a low thermal conductivity and excellent thermal insulation performance. It can reduce the temperature loss inside the processing tank 1 and maintain the temperature inside the processing tank 1, thereby improving the energy utilization efficiency. The zinc ash is then reduced to metal zinc vapor, and then the fan 7 is started. The operation of the fan 7 drives the internal blades to rotate to generate negative pressure. Since the connecting box 17 is connected with the exhaust hood 9 and the processing tank 1, the exhaust pipe 8 cooperates with the exhaust hood 9 to extract the metal zinc vapor inside the processing tank 1, and then the metal zinc vapor is discharged into the recovery box 6 through the outlet pipe 16 for centralized collection. The metal zinc vapor is cooled by the condenser 15, and the metal zinc vapor is solidified into metal zinc powder and gathered at the bottom of the recovery box 6. The surfaces of the discharge port 10 and the discharge port 2 14 are both equipped with control valves, which can be opened to discharge it from the discharge port 10 later. The discharge port 2 14 is used to discharge the raw materials inside the processing tank 1 later.

[0040] like Figure 1 and Figure 4As shown, since the filter plate 18 is located inside the connecting box 17, when the fan 7 is running to extract the metal zinc vapor, the solid particles associated with the metal zinc vapor during extraction can be intercepted outside by the filter plate 18, thereby reducing the situation of extracting solid particles, and the inside of the connecting box 17 and the bottom of the filter plate 18 are connected by a pull-out connection, and subsequent personnel can lift the handle upward to remove the filter plate 18 from the through groove inside the connecting box 17, which is convenient for subsequent cleaning or replacement.

[0041] like Figure 2 and Figure 5 As shown, the stirring and cleaning assembly consists of a motor 3, a rotating shaft 12, a stirring rod 21, a connecting frame 19 and a cleaning plate 20. The connecting frame 19 connects the cleaning plate 20 and the rotating shaft 12. The operation of the motor 3 drives the rotating shaft 12 at the output end to rotate. A plurality of stirring rods 21 equidistantly installed on the surface of the rotating shaft 12 fully stir and mix the internal raw materials. At the same time, the cleaning plate 20 installed at one end of the connecting frame 19 rotates simultaneously with the rotating shaft 12, and cleaning bristles are provided on the surface of the cleaning plate 20, and the cleaning bristles are continuously in contact with the inner wall of the processing tank 1 during the rotation process, thereby sweeping off most of the zinc ash adhered to the inner wall of the processing tank 1 due to stirring, thereby reducing the adhesion of internal zinc ash.

[0042] In this embodiment: the control circuit of the control panel 5 can be realized by simple programming by those skilled in the art, which is common knowledge in the art. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0043] Working principle: open the sealing cover and put the raw materials into the processing tank 1 from the feed port 4, and then close the sealing cover. The personnel can use the control panel 5 to operate the machine, and fully stir and mix the internal raw materials through the stirring and cleaning components. After fully mixing and stirring, start the electric heating tube 13 and the condenser tube 15. The operation of the electric heating tube 13 converts electrical energy into thermal energy, thereby increasing the internal temperature of the processing tank 1. At the same time, the insulation board 11 is made of polyurethane material with a low thermal conductivity and excellent thermal insulation performance. It can reduce the temperature loss inside the processing tank 1 and maintain the temperature inside the processing tank 1, thereby improving the energy utilization efficiency. The zinc ash is then reduced to metallic zinc vapor, and then the fan 7 is started. The operation of the fan 7 drives the internal blades to rotate to generate negative pressure Since the connecting box 17 is connected with the exhaust hood 9 and the processing tank 1, the exhaust pipe 8 cooperates with the exhaust hood 9 to extract the metal zinc vapor inside the processing tank 1, and the metal zinc vapor passes through the filter plate 18 inside the connecting box 17 during the extraction process to intercept the fixed particles and prevent the solid particles from being extracted into the recovery box 6. Then the metal zinc vapor is discharged into the recovery box 6 through the outlet pipe 16 for centralized collection. The metal zinc vapor is cooled by the condenser 15, and the metal zinc vapor solidifies into metal zinc powder and gathers at the bottom of the recovery box 6. Control valves are installed on the surfaces of the discharge port 10 and the discharge port 2 14. The control valve can be opened later to discharge it from the discharge port 10. The discharge port 2 14 is used for the subsequent discharge of the raw materials inside the processing tank 1.
